Answer:
8,324,608 chromosome combinations
Explanation:
During meiosis, chromosomes separate independently so that only one chromosome came from the father and the other homologous chromosome came from the mother. This process of independent assortment produces a huge amount of possible combinations in the diploid zygote cell. In humans, the haploid number of chromosomes is n = 23, thereby there are 2²³ = 8,324,608 chromosome combinations. Thus, the independent assortment of chromosomes during meiosis is a key factor that contributes to genetic variation in the offspring.

Methamphetamine increases the brain's levels of dopamine, __________ and __________.
a) norepinephrine, serotonin
b) GABA, epinephrine
c) acetylcholine, enkephalins
d) glutamate, serotonin
Answer:
a) norepinephrine, serotonin
Explanation:
Neurotransmitters are special lipid-based molecules used in chemical signal transduction in the nervous system. They have receptor-specific roles in activating different regions of the central nervous system (CNS) and physiological responses. These include: dopamine, norepinephrine, and serotonin .
The CNS, which includes the brain and spinal cord, can be affected by certain drugs like methamphetamine. This drug is a stimulant that acts on brain regions such as:
prefrontal cortex the striatumthe nucleus accumbensIt causes the release of neurotransmitters while blocking their reuptake at synapses; meth is metabolized very slowly over time (12 hours). The buildup of dopamine, for instance, leads to altered moods, feelings of pleasure and euphoria.
Thus, this change or "high" leads to dependency by users for its mood-altering effect; however, less dopamine is released, and the pleasurable effects, become less potent. Studies show neurological damage with prolonged use, and habit formation and over time, addiction.

Which of these is a condition where the endometrial lining that is normally supposed to only be inside the uterus, ends up outside the uterus (for instance, in the pelvic cavity) and causes extreme pain during menstruation? This condition affects up to 1 in 4 women.
Answer:
Endometriosis is called the pathology
Explanation:
Endometriosis is a pathology where fibroblasts or connective tissue cells proliferate outside the fallopian tubes in the abdomen, close to the intestine, and adjacent to the ovaries, by proliferating and reducing the space between the organs, the pressure of the terminals increases nervous and during menstruation it hurts.
They are benign proliferative cell foci.

Solution : It is a mixture of solvent (Major component mostly liquid) and solute (Minor component).
It is asking from a solution where water and solute are moving whether outise or inside.
_____________________________________As Per Hint Given:Solute ; Moves from higher concentration to the lower concentration by the process of diffusion.Solvent(Water) ; Moves from low solute area to the high solute area by the process of osmosis._____________________________________ROW 1 :26: Inside the cell (because inside the cell there is 5% solute(salt) whereas outside the cell it is 10%)
27: Outside the cell (outside the cell there is more concentration of salt so water moves out)
ROW 2:In Row 2 there is equal amount of salt outside and inside the cell so Solute and Solvent do not move because the solution is ISOTONIC
28: NO MOVEMENT
29: NO MOVEMENT
ROW 3:30: Glucose moves outside the cell
31: Water moves inside the cell (because glucose is more inside the cell)
ROW 432: Outside the cell (same reasons as above)
33: Inside the cell
ROW 534: NO MOVEMENT
35: NO MOVEMENT
ROW 636: Outside the cell

Which is not a unique property of water
Answer:
A
Explanation:
All of the other options are specific to water, but quite a few liquids cool off a lot faster than water.
water cools very rapidly is not a unique property of water. Thus option A is correct.
what are the properties of water molecule ?It has no taste, odor, or transparency, where the nucleus of the oxygen atom attracts electrons strongly than the nuclei of the hydrogen atoms.
In water molecule oxygen is more electro negative and electron-greedy than hydrogen, results in the development of a partial negative charge on the oxygen of the water and a partial positive charge on the hydrogen end.
Water shows strong cohesive property where the attraction of molecules for other molecules of the same kind is referred to as cohesion.
Surface tension is defined as the tendency of the surface to resist rupture when they are subjected to stress due to cohesive forces.

The passive movement of particles from a region of higher concentration to a
region of lower concentration is known as...
A. Diffusion
B. Active Transport
C. Osmosis
D. Selective Permeability
Answer:
Answer is A. Diffusion
Explanation:
Because diffusion is a passive process in which a substance moves from a higher concentration to a lower concentration until the concentration becomes equal
The passive movement of particles from a region of higher concentration to a region of lower concentration is known as diffusion. Thus, the correct option is A.
What is Diffusion?Diffusion may be defined as the passive movement of particles from a region of higher concentration to a region of lower concentration.
Active transport requires energy for the movement of particles. Selective permeability may be defined as the ability to differentiate the movements of different types of particles in and out of the membrane.
Therefore, the correct option for this question is A.

Humans deplete the most resources when
Answer:
Resource depletion is the consumption of a resource faster than it can be replenished. Natural resources are commonly divided between renewable resources and non-renewable resources (see also mineral resource classification). Use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion. The value of a resource is a direct result of its availability in nature and the cost of extracting the resource, the more a resource is depleted the more the value of the resource increases. There are several types of resource depletion, the most known being: Aquifer depletion, deforestation, mining for fossil fuels and minerals, pollution or contamination of resources, slash-and-burn agricultural practices, Soil erosion, and overconsumption, excessive or unnecessary use of resources.
Resource depletion is most commonly used in reference to farming, fishing, mining, water usage, and consumption of fossil fuels. Depletion of wildlife populations is called defaunation.
Explanation:
Why do planets close to the sun have thin atmospheres and the planets far away from the sun have thick atmospheres. Use what you know about the nebular theory.
Answer:
There are two primary factors: size and distance from the Sun. Gravity helps planets and moons to hold on to their atmospheres, so small planets/moons such as Mars and the Moon have thin atmospheres. The reason why the outer planets are larger is probably down to two major factors. The first is simply the amount of material available which may be accreted to a planet. Clearly, the further away from the Sun, the longer the orbit (twice as far means an orbit twice the physical length).

The number of waves passing the observer per second is:
- the wavelength
- the amplitude
-the frequency
- the period
Answer:
frequency
Explanation:
comment if im wrong
The number of waves passing the observer per second is the frequency. Hence, the correct option is C.
What is frequency?Frequency refers to the number of waves that pass from a fixed point in unit time. It is a measure of the rate of repetition of a periodic phenomenon such as vibration or a wave.
It is measured in hertz (Hz), an international unit of measure where 1 hertz is equal to 1 cycle per second. The more cycles that occur per second, the higher the frequency of the system is.
For example-The human heart beats at a frequency of 68 beats per minute.
In general, frequency is a very important concept in many fields including physics, engineering, music and the natural sciences, and it is used to describe and analyze a wide range of periodic phenomenon.
Therefore, the correct option is C i.e., frequency.

Which label identifies the part of the ATP molecule that changes when energy is released in the cells of all living
things?
B
Р P Р
A
A
B
C
Answer: Respiration
Explanation:
Cellular respiration is the process by which nutrients such as glucose are broken down using oxygen to generate energy in the form of ATP, that is used to drive cellular processes.
ATP consists of an adenosine molecule bonded to three phosphate groups in a row. Energy from cellular respiration is stored in the bond between the 2nd and 3rd phosphate groups of ATP.
When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.
